Application filed June 7, 1912. Serial No. 702,217.

To all M72092). it may concern Be it known that I, CARL F. Gniuaivonn, acitizen of the United States, residing in Dallas, in the county of Polkand State of Uregon, have invented certain new and useful Improvementsin VVater-Gages, of which the following is a specification.

My invention relates to water gages of the kind commonly employed toindicate the water level in steam boilers. There are several kinds ofsuch gages in general use but my invention more particularly relates tothe kind in which the gage comprises a casing or frame supporting apiece of glass constituting the front wall of a chamber whichcommunicates with the boiler and in which the water rises and fallscorrespond ingly with the water level in the boiler.

The object of my invention is to provide a gage of this general typewhich is simple in construction, may be easily put together and takenapart, is leak-proof, may be easily inspected or observed from varioussides and may be easily cleaned or repaired.

In carrying out my invention i provide a main frame constituting theback, top and bottom of the casing or frame and form integrally with thetop and bottom parts of this main frame nipples to which suitable pipesmay be easily connected. Between the top and bottom of the main frame Iinterpose the glass front wall of the water chamber and then apply thefront frame which has front and side openings to expose the glass, andupper and lower covers for the front portions of the top and bottomparts of the main frame, also side portions which cover those portionsof the main frame on opposite sides of the glass. The front frame isprovided with flanges at top and bottom and on opposite sides whichoverlap the edges of the main frame. The gage thus comprises three mainparts and these are so shaped that they may be very readily assembledand the glass front secured in the back frame between the top and bottomparts by merely applying the front frame.

The top and bottom parts of the main frame are formed on their innersides with seats for the glass which aid in positioning it, and suitablepacking is applied in an improved way to prevent leakage and to insure atight and firm connection. The front and back parts of the frame aresecured together by screws and may be easily separated for repairs orcleaning purposes.

In the accompanying drawings, Figure l is a perspective view of a watergage embodying my improvements. Fig. 2 shows a vertical central. sectionthereof. Fig. 3 shows a transverse section on the line 33 of Fig. 1.Fig. 4 shows a transverse section on the line 4% of Fig. 1. Fig. 5 is aperspective view of the main frame. Fig. 6 is a perspective view of theglass front. piece of the water chamber. Fig. 7 is a perspective view ofthe front frame viewed from the rear. Fig. 8 is a perspective view ofpacking which may be employed to form a water tightjoint between theglass front and the back frame. Fig. is a perspective view of packingwhich may be employed between the front frame, the glass and the backframe.

The main frame comprises a back part A, a top part B and a bottom partC. The back part is of a general. rectangular form and is provided withshallow vertical grooves or recesses a to receive the edges of the glassG or the packing strips hereinafter described. The top and bottom partsare frus tum shape and are arranged above and below the panel a formedbet-ween the grooves a. At the top and bottom of the panel there areseats A A for the glass G. These are of smaller dimensions than the topand bottom B and C, so that the glass may bear against the seats and bearranged within the limits of the top and bottom pieces. he top andbottom pieces 13, C, are formed integrally with nipples D, D, andopenings or channels extend through the nipples and through the top andbottom pieces and the seats into the chamber X.-

The glass G, as shown in Fig. 6, is threesided, having a front 9 andinclined sides 9.

This glass is of such length as to fit easily between the top and bottompieces B and C and its vertical rear edges lie opposite the grooves a,while its upper and lower parts rest against the seats A A Packing isinterposed between the glass, the seats and the grooved portions of theback frame in the manner hereinafter described.

The front frame comprises side pieces H, a middle part H, and top andbottom parts H The top and bottom part-s of the frame cover the frontportions of the top and bottom parts B, C, and also parts of the upperand lower ends of the glass. These parts H H are connected by strips orbars I which are so arranged as to leave three 0bservation openings J,J, J Flanges m 6X- tend around the outer edges of the sides and the topand bottom portions of the main frame, and also around the edges of thesides of this frame, and when the front frame is thus applied the glassis held in place, screws N being employed to securely fasten the partstogether. In this way a chamber X is formed which connects with thenipples at the top and bottom of the gage and these nipples may besuitably connected with the boiler in any usual way.

In order to render the gage leak-proof, packing of suitable constructionmay be employed. 1 preferably employ packing like that shown in Fig. 8,which comprises side portions P and upper and lower portions P, P. Whenthe packing is shaped in the manner indicated in Fig. 8, it will fit inthe grooves a and around the top and bottom seats A of the main frameand when the glass G is applied, a packed joint is provided whichprevents leakage from the chamber X.

In order that the front frame may be secured without undue pressure onthe glass, or rather to keep the front frame from direct contact withthe glass while connecting it with the back frame, I preferably employpacking of the kind indicated in Fig. 9 which comprises side parts Q andupper and lower parts Q, Q The side portions Q are interposed betweenthe front 9 of the glass and the connecting strips or bars I, while theupper and lower parts Q, Q are interposed between the glass and theupper and lower parts H H of the front frame. In this way the screws maybe tightly driven so as to press the glass tightly against the packingand the latter is tightly pressed to its seats in the main frame. Thepacking shown in Fig. 9 also serves to supplement the packing shown inFig. 8 as an additional protection against leakage.

I claim as my invention:

1. A watergage, comprising a main frame having a back part, top andbottom portions formed integrally with nipples for pipe connections andwith seats for the glass front of the gage, a glass front arrangedbetween the top and bottom portions of the main frame and inclosing saidseats, and a front frame covering the side portions of the main frameand the top and bottom portions thereof and which is provided with frontand side observation openings.

2. A water gage, comprising a main frame formed with top and bottomportions and with vertical grooves in its front face, a glass arrangedbetween the top and bottom portions of the frame, seats on the mainframe covered by the glass, packing interposed between the seats and theglass and arranged in the grooves of the back frame, and a front frameattached to the main frame and having front and side observationopenings.

3. A water gage, comprising a back frame formed with top and bottomportions and with seats for the glass of smaller area, a glassinterposed between the top and bottom portions of the frame and coveringsaid seats, packing interposed between the glass and the seats and thevertical edges of the glass and the back frame, a front frame coveringthe exposed parts of the back frame and having front and sideobservation openings, and means for securely fastening the front frameto the back frame.

4. A water gage, comprising a back frame formed integrally with top andbottom portions having integrally formed nipples and integrally formedseats for the glass front, a glass front interposed between the top andbottom portions of the frame and covering said seats thus forming awater chamber, packing interposed between the seats, the back frame andthe glass, a front frame covering the glass and the main frame havingfront and side observation openings, and packing interposed between thefront frame, the glass and the back frame.

In testimony whereof, I have hereunto subscribed my name.
